When you think you can join the army an respawn after dying in war. ( already been said but came up in a convo of mine with some friends)
or
When you want to join the military just to be a sniper to try an 360 no scope someone "across map" and if you so happen to make this impossible shot you know you would yell "Get NO SCOPED!!"
(again came up with some friends of mine lol)
